I got the interview through a university career fair.

The first interview was quite easy, but the second was really hard.

I was asked questions about material for which I had not yet taken the classes, and the interviewers did not seem to care.

They continued to ask me questions about topics not taught at all at the university, which only professionals or experts in C++ would know, rather than the general conceptual, algorithmic, or brain teaser questions that I have encountered in previous interviews.

Also, there were no behavioral questions in the two hours of interviewing.

Regarding the destructor for non-dynamically allocated variables (variables on the stack, not the heap), you can override this using a library that nobody I've asked on campus has ever heard of.
